The function of the ignition coil is to transform the voltage of the power system of the vehicle, it usually ranges from 12 to 14V for high voltage. This high voltage can reach 45.000V. The high voltage coil is driven by the ignition wires to the spark plugs, where it is converted into a spark that will start the fuel-burning reaction.  The NGK spark coils are manufactured to the strictest quality criteria NGK Brazil. Taking this way the quality and NGK technology to the entire ignition system of your vehicle, the coil to the spark plugs. The principle of operation of the ignition coils is based on the principle of electromagnetic induction. The primary coil circuit receives a current from the power system. The variation in the primary current generates a magnetic flux variation in the coil, inducing a voltage in the secondary. This tension is responsible for the generation of electric spark in spark plugs.
